One issue I have with hosted-engine is that when something goes wrong it has a domino effect because hosted-engine cannot communicate with its database. I have been thinking to host ovirt engine separately on a different hypervisor and have all my host undeployed. However for efficiency my networks are separated by their functions. So my questions are as follow

1) is it a good idea to host the engine on a separate kvm

It is, for certain cases.

2) what network does this engine need to access. Obviously ovirtmgmt, and display to access it but what about storage. Does it need access to itor can it access it through ovirtmgmt and the SPM?

The engine does not need access to the storage network. It does all storage operations through hosts.

3) Is there a recipe or howto available to follow

This was discussed several times on this list, also recently - please check archives. Some people claimed they had bad results using the search function on the website. You can also use your favourite search engine - most allow e.g. 'site:lists.ovirt.org something'. Good luck and best regards, -- Didi
